Event-Related Potentials

Q: Why we use ERPs

A:  The ERP waveform consists of a series of positive and negative voltage deflections, or "peaks," that mark the passage of information through the nervous system. Since each peak has its own characteristic latency and scalp distribution (i.e., pattern of voltage gradient over the scalp), the ERP as a whole provides an index of the timing, extent and intactness of information processing activities at a wide range of levels within the central nervous system. The temporal characteristics of ERP components make them ideal candidates for quantifying the timing of sensory and cognitive processes. Their millisecond (ms) time base makes ERPs sensitive to even subtle changes in neural transmission or processing time.
Q: How are ERPs obtained?
A: We record brain waves (i.e., electroencephalogram or EEG) to provide us with a measure of task-related brain activity. To do this, we place a sterilized bathing cap-like device that is lined with electrodes on the participant's head that will allow us to measure and record your brain waves as you perform several tasks. The procedures used are all non-invasive and the electrodes do not make contact with the participant's scalp. We do not do anything to the participant's hair. There is NO risk of any kind associates with this equipment. We will NOT be gluing anything to you head and will simply be placing electrodes encased in plastic resting on your scalp. We do however, use a conductive gel to fill the plastic enabling us to record your brain activity. This gel is water-soluble and washes out with shampoo. You will be able to see your brain waves during the experiment.

Participation FAQs

Q:  What are your criteria for inclusion in a study?

A:  You must be a Native English Speaker (have learned English by age 6).
You must have normal or corrected to normal vision and hearing.
You must be right handed.
You must have NO history of, or be taking medications for High Blood Pressure, Psychiatric Disorders or Diseases (eg. depression, anxiety, or mood disorders), or Neurological Disorders or Diseases (eg. stroke, head injury, epilepsy, seizures, brain tumors, brain surgery, Parkinson's Disease). Birth control pills and over the counter medications are acceptable.
No history of head injury, loss of consciousness, or seizures.

Q: How much will I be compensated for my time?

A:  Every participant is paid $10/hour for all time spent in the laboratory and performing experiment-related activities (e.g., answering questionnaires, learning lists). You will receive payment in cash at the end of the ERP recording session.

Q: What will I be doing?

A:  In these studies, participants sit in front of a standard computer monitor and make decisions about what they are shown. For example, in a memory test, participants respond with a particular button if they have seen the item before and a different button if they have not seen the item before.

Q: My spouse or friend is interested in participating as well. Can the two of us participate in the same experiment?

A:  Yes. While we don't have the facilities to run both of you through the experiment at the same exact time, we can stagger your activities.
